In this issue, we revisit the topic of real-time data. First, we have a fresh set of data, made more useful by the fact that we can compare it historically to the previous survey. Second, we have a solid "bird's eye" view of the DDS space through the high-level conceptual framework articulated by Federico and Gabe. And, third, we have a very pragmatic "nuts and bolts" view of the same space from Manjunath.
